Respiratory infections

Aspergillosis is a spectrum of diseases of humans and animals caused by members of the genus Aspergillus. Aspergillosis is primarily an infection of the lungs caused by the inhalation of airborne spores of the fungus Aspergillus. Aspergillosis is caused by a fungus (Aspergillus), which is commonly found growing on dead leaves, stored grain, compost piles, or in other decaying vegetation.

Avian influenza is a contagious disease of animals caused by type A strains of influenza viruses that normally infect only birds, and sometimes pigs. Avian influenza viruses (of which there are 15 types) infect wild bird populations, particularly water birds, typically without causing symptoms. The virus spreads through bird faeces and contaminated water or dust.

A cold is a viral infection that affects the upper airway including the nose, pharynx, throat, airways, and lungs. The common cold is a viral infection of the upper respiratory system, including the nose, throat, sinuses, eustachian tubes, trachea, larynx, and bronchial tubes. The common cold is caused by numerous viruses infecting the upper respiratory system.

Influenza, usually known as the flu, is a respiratory infection caused by one of the influenza viruses that typically is spread by air or by direct contact. Influenza is a highly infectious respiratory disease. The disease is caused by certain strains of the influenza virus. Influenza is spread through contact with droplets from the nose and throat of an infected person during coughing and sneezing.

Croup is breathing difficulty accompanied by a "barking" cough. Croup, which is swelling around the voacl cords, is common in infants and children and can have a variety of causes. The symptoms of croup are caused by the swelling and inflammation of the tissues around the larynx and vocal cords. Croup is usually caused by the parainfluenza virus, although there are many other possible viral causes.

Legionnaire's disease is an acute respiratory infection caused by the bacterium Legionella pneumophila, which can cause a broad spectrum of disease from mild cough and fever to a serious pneumonia. Legionnaires' disease is a type of pneumonia that is caused by Legionella, a bacterium found primarily in warm water environments. Legionnaires' disease develops 2-10 days after exposure to the bacteria.

Pneumonia is an infection of the lungs. It involves the tiny air sacs, called alveoli, which are located at the tips of the body’s smallest breathing tubes, called the bronchi. The alveoli are responsible for passing oxygen into the blood. Pneumonia is usually triggered when a person's defense system is weakened, most often by a simple viral upper respiratory tract infection or a case of influenza (the flu).

Respiratory syncytial virus (RSV) is a very common virus that causes mild cold-like symptoms in adults and older healthy children. It can cause serious respiratory infections in young babies, especially those born prematurely, who have heart or lung disease, or who are immunocompromised. RSV is a negative-sense, enveloped RNA virus. Respiratory syncytial virus, or RSV, is a virus that attacks the mucous membranes of people's respiratory tracts.

Whooping cough (pertussis) is a highly contagious bacterial infection of the upper respiratory system - specifically, the area where the nasal passages meet the back of the throat (nasopharynx). The infection causes irritation in breathing passages, resulting in severe coughing spells. The illness has three distinct stages and can last months. Pertussis, also known as whooping cough, is caused by infection with the Bordetella pertussis bacteria.
